Minutes - Special Meeting Solid Waste Advisory Board March 31 , 2009 Approved May 7, 2009 the transfer station and the long haul tractor-trailers . The equipment type and operating cost are based on county experience and other operating facilities . The results of this on a net present value are the economic tool to get you to a true apples-to -apples comparison . We understood from the beginning from the Commissioners we were to look at the alternatives and looking at alternatives to getting to a long-term solution. We know that the Hwy 54 site is not going to be appreciated by the people that live around it any more that any other site . The issue for us is not if [Hwy] 54 is a good site or not or should you look for another site . The County has gone through an elaborate siting process that got to this point. You don' t want to abandon that totally because people around that site don' t like it. There is no such thing as a perfect site . What has to be considered to put a site here, is it a permanent site or not. We assume if it is, 20 year cost analysis is your best cost for that site . We also noted that any alternative will take more than a few years to develop . Cost Summary - 20-Year Net Present Value Option Cost West Hwy 54 Transfer Station $55 Million Durham Transfer Station $ 62 Million WI / WM Transfer Station $ 65 Million We also looked at some emissions . We used the additional off route emissions based on heavy- duty diesel vehicle emissions . The information is from an EPA study by INFORM . We did some correlation of the amount of tons that would be accumulated over the 20 year period . In reality this isn' t a lot of tons . We were also asked to look at some relative risks and impacts . The thing that sometimes gets lost in this is the headache of the one that has to run the vehicles for the Towns and County . Those that drive the vehicles have more risk the farther they have to drive . They will have a [mechanical] breakdown . There will be accidents . They will slowed down because of other accidents . So we looked at relative risks and grouped them high, medium and low . Other issues that we looked at based on our experience with a local government not owning its transfer station, it reduces the flexibility to use alternative long- term disposal options . If you want the best deals from the private guys you have tap into a longer term contract which locks you out of any other options during that period of time . There is less influence on the disposal site operations to ensure environmental health and safety . The reduced ability to take advantage protection and community of improved disposal costs at alternative locations is similar to the alternative technology but it is more of landfilling [alternative] .
